Description

Osmunda regalis (Royal Fern)

Royal Horticultural Society Award of Garden Merit (AGM)

This fabulous decorative fern is probably the best of all for architectural effect, and although it looks tender, it is in fact completely hardy, improving in stature yearly.

The family Osmundaceae is an isolated and primitive group with no close relations, Osmundaceae fossils being known from as far back as the Permian (290-248 million years ago), while modern Osmunda fossils have been found in Upper Cretaceous sediments (up to 65 million years ago).

The “Royal” name derives from its being one of the largest and most imposing hardy European ferns. This unique, deciduous, herbaceous plant which produces separate fertile and sterile fronds, is now very rare as a result of wetland drainage for agriculture.

It is sometimes known as flowering fern due to the appearance of its fertile, spore-producing fronds which appear on the ends of the fronds, (rather than underneath) producing a most attractive contrast.

Prefers full sun or semi-shade. Grow in full sun, likes damp root conditions.

Height and spread: 2.5 metres x 1 metre
